I can reproduce the crash here so I can see if I can find the cause. However, the failure is happening in the _server_. Threading is unrelated to the server itself, only the client. I suppose the first test for me will be to test CVS before the thread change was made. The failure is in heap_fill_tuple(), and I am unclear how that assert could be getting triggered: CONTEXT: automatic analyze of table "test.public.pgbench_accounts" TRAP: FailedAssertion("!((data - start) == data_size)", File: "heaptuple.c", Line: 255) TRAP: FailedAssertion("!((data - start) == data_size)", File: "heaptuple.c", Line: 255) TRAP: FailedAssertion("!((data - start) == data_size)", File: "heaptuple.c", Line: 255) LOG: server process (PID 6076) was terminated by signal 6: Abort trap LOG: terminating any other active server processes -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
